    摘要:

    MXene作为一种新型的二维纳米材料,拥有优良的导电性,在柔性力敏材料领域有广泛的应用前景。为了构筑柔性力敏材料,通常将MXene与柔性聚合物或多孔聚合物相结合,从而实现柔性及大形变。柔性力敏材料中,MXene的分布、导电网络结构与形态由制备方法决定,进而决定传感器的类型和应用类型及场合。文中从MXene柔性力敏材料的制备策略角度出发,总结了浸渍法、喷涂法、真空过滤法、冰模板法及其它方法对MXene柔性力敏材料性能的影响,同时归纳了MXene柔性力敏材料在生理信号、细微人体动作、关节运动信号监测以及对信号进行示踪等方面的应用进展。

    Abstract:

    As an emerging two-dimensional material, MXene has excellent conductivity and wide applications in flexible electronics, such as forcing-sensitive material, electromagnetic shielding material, supercapacitor and so on. As MXene has a layered structure, the sheets will slip between each other under strain. And the MXene sheets are easy break under stress due to the high modulus of MXene. In order to construct flexible force-sensitive materials, MXene usually combines with flexible matrix or cell structure like sponge to achieve flexibility and large deformation. The distribution of MXene, structure of conductive network and mechanism of forcing-sensitive materials were decided by preparation methods. Thus, the fabrication of MXene based flexible force-sensitive materials that could resist large deformation with simple and efficiency methods is the key factor to broaden MXene applications. This review summed the methods, including dipping method, spraying method, vacuum filtration method, ice-template and some other methods and their effects on the performance of flexible MXene forcing-sensitive materials. Meanwhile, the applications of flexible sensors in monitoring physiological signals, subtle human movements, joint movement signals and signal display were also summarized.
